Application filed October so, 1917. Serial miisaasag I at the bottom of the stylus reservoir and free to reciprocate across the same is a selector slide 25, to which reciprocating move ment may be imparted from a lever 26 which the selector slide and engages an ear .27 on isprovfided with a push button 28 whereby 1tcan be readily rimanipulated,,.acoiled spring 29 serving to lever 26 in the position shown in Fig. 2, that is to'say, with the selector slide 25' fully retracted and the lowermost stylus in the reservoir 2 occupying a; position in a shown in Fig. 8.

At the bottom of the-reservoir 2 is a forwardly projecting flange 31'from which depends the chute 3, therein a slot 32 with, opposite pointed ends, as shown in Fig. 10. j a

-VVhen the selector lever .26 is depressed the "selector slide 25 is caused to move for wardly and the stylus occupying the slot 30 in said slide is brought .into line with the 31 of the reseryoir and drops through said slot into'the chute 3, the pointed end of the stylus passing through the corresponding end. of the slot and the butt end of the ,stylusibeing retained by the opposite. pointed 'end'of said slot so as to. upend the stylus and feed it point down through the chute "3 and into the upper flarlng end of the holder 20 through which it likewise passes point down until it reaches the adjusting, gripping and retaining mechanism; at the lower end of said holder. v i The adjusting, gripping and retaining mechanism is as follows:,

'In a boss33 on the face of the.

which is moved in one direction by a spring 35 and in the otherldirection by a lever between boss 3 3fand the head 37 of 38. which is mounted upon and moves with the cam slide 3i, and

one end of the projects forwardly below the lower end of the tubular stylus holder 20, as shown in 1 and 3,. said projecting portion of the adjusting plate having therein a V- shaped slot 39' with the mouth of the V at the outer en'd of the plate, as shown in fFigs. 6 and 7,

The lever 36 is normally free from contact normally maintain the said, flange having M I holder 20 isfree tomovelaterally a cam slide 34 "transverse slot .30 in, the selector slide, as

with the head37, so that it will exert no rest-raininginfluence upon the freedom of vibrabion of the stylus lever. Vhen the cam slide 31t 1slm oved in one direction'across the tubular stylus holder its cam freed from-contact with the stylus the lever 26 is depressed or movedin the. di-'- rection of the arrow, Fig. 2, the-C3111 disk 47. will likewise be moved in the direction of the v .by' the time the fresh which is in operativeposition in the lower part of said holder, as' shown 111 Fig. consequen'tly said stylus is free to drop from the. holder and to be replaced bya fresh stylus delivered point downirom the feed chute 3, movementof the cam slide; 34 from the-position shown in Fig.5 to that shown in Fig. --l causing said N clamped in the lower port-ion. of theholder, as shown in Fig. 4.

stylus to be firmlv When the cam 4O releases wornstylus'and permits the latter to'd-rop from the holder "20 the adjusting plate 38 has, I e not advanced far enough to interfere with the freedischarge of said worn stylus, but,

' stylus has dropped into-the holder the slot 3..9 will have advanced to the position shown in Fig. 7 and the taper,-

ing point of the stylus will engage the walls Of the slot tained in its proper in the holder 20, the

39 and said stylus will thus be reposition of adjustment gripping of the fresh stylus by .the cam 40 on the retraction of the sl1de31 preventing the release of the stylus asthe walls of the slot 39 are withdrawn from contact with. theta'pered end of said stylus. 86

I may, 'in some cases, use an unslotted adjusting plate which arrests the downward movement of the fresh stylus [by contact with the point of the same, but the'slotte'd adj usting plate is preferred because it effects the desired adj'ustnien of the stylus without riskof dulling the point of the same.

Proper action of the lever 36 upon the cam slide 34 is effected on each-operation o'f-thc stylus selecting lever 26 in the following manner At one end of the pivot. shaftof the lever 26 is' a segmental .rack 42 which meshes with a pinion -13 free to turn upon a pin 44 which projects from one side of the stylus reservoir 2, asshown in Fig. 11. This pinion has a ratchet toothed-huh 45, the teeth of-whiclrengagewiththose ofa ra-tcheted hub 46 on a cam disk lTlikewise free to turn on the pin H and also to slide lon 'tudinally thereon, said disk being normal y retained in the position; shown In F1gs..2 means of a' co le'd spring -18 contained .in the recessed face ofthecam disk -l7 and inter-. posed between the base of said; recess anda plug 49-which bears against the head of the pin 44, as shown in Fig. 11. When therefore arrowshown thereon and the lever 36 will be operatedso asto come into'contact with the lever 26, its hold upon the V-shaped slot in the as shown in Fig. 6,]

Q38, the used va'n'ce of the peated as soon'as, each worn ;moving the same hack a and 11 bya, stylus gripping and lever for acting on said gri ping device,

head 37, and then to impart forward movepartial turn due to the backward movement of the lever 26. On eachoperation of said therefore, a selected stylus will be delivered by the selector slitle 2.5. to the slot-ted'upper end of the. delivery chute 3, will be upended and delivered pointfirst fromsaid chute 3 to the holdlr 20 and will pass throughthe latter .until its. forward movement isarrcsted 'bythe adjusting plat-c stylus being discharged in ad. fresh one and the latter being then firmly gripped by the cam slide 34 in proper position for engagement with the record.

In order to prevent any back movement of the fresh "stylus under the pressure. of the record a retainer plate 50 carried by the cam slide i "as shown in Fig. 1, insertedbehind the fr sh stylus, as the cam slide moves to the gripping position shown in-Fig. 4; and the parts remain in this position as long asthc stylus is in action, the. operations being restylus is discharged and a -fresh' one is inserted in place of the same;

A .weight 51 isapplied to one arm ofthe stylus lever 21, as shown in Fig. 1, in order to counterbalance the weight, on the other 'arm of said lever, of the stylus holder and of the parts carriedt'he-reby, free movement of the stylus by the record being thus permitted and deadening of thesoundof the record thereby prevented. Iclaimz' '1. The combination 'of the-stylus holder, a stylus'gripping and releasing device 00111-5 prismg'a .cam ;s lide,'-m'eans for guiding the same for movement 'in a direction transverse toi'the axis of the styluls, means for forth in said guide, and an adjusting device carried. by andmovable with said-"cam Slide, said ad-' justing device. having, a member projects ing below the tylus holder and having a V-shaped slot tl erein for arresting down: ward movemenflibf the stylus through the holder whenthe cam slide is in the releasing position." ,.'2.
